Recent UK guidelines on the decontamination of ENT endoscopes provide important insight into the environmental impact of commonly used disinfection methods. For ENT clinics aiming to balance clinical safety with sustainability, this evidence-based information offers a timely opportunity to review current practices.
UV-C Disinfection: Effective and Environmentally Conscious
The guideline now includes UV-C light disinfection as a validated method. This process consists of a manual pre-clean using water and a microfiber cloth, followed by a60-second UV-C disinfection cycle. According to referenced studies in the guideline, UV-C disinfection achieves microbial reduction on par with washer systems, with no statistical difference in colony-forming units on nasoendoscopes.
Environmental impact figures cited in the guideline include:
- Electricity usage per cycle: Approx. 0.01 kWh (equivalent to 0.0029 kg CO₂)
- Estimated annual clinical waste per ENT consultant: 2.8–4.4 kg (from microfiber cloths)
- Estimated annual CO₂ emissions from incineration per ENT consultant: 3.1–4.4 kg
Washer Disinfectors: High Resource Consumption
According to the guideline, Endoscope Washer Disinfectors (EWDs), while effective, are associated with high resource use:
- Water consumption per cycle: 100–136 liters
- Electricity usage per cycle: 0.62–1.3 kWh
- Estimated annual CO₂ emissions per ENT consultant: 126–590 kg
Each cycle takes between 22 and 45 minutes, which can pose challenges in high-throughput outpatient clinics.
Wipe-Based Disinfection: Flexible but Waste-Intensive
The same UK guideline reports that wipes are non-biodegradable and must be disposed of as clinical waste. This results in:
- Estimated annual clinical waste per ENT consultant: 35–45 kg
- Estimated annual CO₂ emissions from incineration per ENT consultant: 34.65–49.5 kg
While wipe-based methods offer flexibility, they contribute significantly to waste volumes, particularly in clinics with frequent scope use.
These findings suggest that UV-C disinfection can reduce clinical waste by up to 10 times compared to wipes, and energy consumption by up to 600 times compared to washer systems, while maintaining high standards of safety and efficacy.
For ENT clinics aiming to reduce their environmental footprint, improve efficiency, and uphold high hygiene standards, these findings offer valuable perspective. The data suggests that UV-C disinfection is not only clinically validated but also presents a more sustainable alternative. This guideline may serve as a practical step for clinics looking to align with long-term healthcare and sustainability goals.
